I will endeavour to make orders available within a couple of days but if I am unable to fulfill orders in this time frame I will contact you. In cooler weather the polyurethane seal takes longer to harden and it is not wise to rush this process. For bulk orders I am happy to offer a discount.  Please contact me to discuss this. Product The mats are cork based with hardboard tops which are lacquered with layers of polyurethane.  Being handmade there will be imperfections from time to time.  They will withstand moderate heat but not hot dishes straight from the oven. Freight Delivery costs are calculated through the shopping cart on the website. The mats are wrapped in tissue and covered in bubble wrap for safe postage in a New Zealand Post bag. Postage anywhere in New Zealand up to 3kg in weight is $6.30. Over 3kg will require a quote.
